Problems solved by technology

[0010] The MDT system and method flow in the prior art have the following defects: lack of MDT start trigger mechanism
According to the existing minimum drive test process, the UE will not know when to report the capability information and start the minimum drive test process; the network has no way to trigger this process, so the operator has no way to control MDT. what businesses don't want to see

Embodiment 1

[0033] The MDT system proposed in Embodiment 1 is as follows: figure 2 shown. In order to solve the problem that the network side and the operator cannot trigger the MDT process, the MDT system makes the following improvements on the basis of the existing technology:

[0034] The network entity 101 adds an MDT control module 108 . The MDT control module 108 is used to realize the control function of MDT, such as triggering the MDT process, including starting or closing the MDT; and other related MDT control processes, such as setting a specific area and / or a specific time period (such as When it is low) carry out MDT, etc.;

[0035] Before the reporting of UE log and reporting capability information in the existing MDT implementation process, a new step related to triggering MDT is added. It specifically includes: when the operator wishes to control the MDT, the MDT control module 108 of the network entity 101 sends an MDT control message to the UE 102; the UE 102 reports ...

Embodiment 2

[0061] The MDT system that embodiment two proposes is as image 3 shown. In this embodiment, the MDT function is integrated into the O&M strategy and requirement enhancement module 103 , and the O&M strategy and requirement enhancement module 103 includes an MDT control module 108 .

[0062] based on image 3 The MDT process of the shown MDT system is as follows:

[0063] Step 301: When the UE 102 is performing a radio resource control (RRC) connection, the UE reports related logs and reporting capability information to the network entity 101 .

[0064] Step 302: The MDT control module 108 of the network entity 101 decides to enable MDT, and after the operation and maintenance policy and requirement enhancement module 103 stores the capabilities reported by the UE, sends log configuration information carrying signaling whether to enable MDT to the UE 102.

[0065] Step 303: The operation and maintenance policy and requirement enhancement module 103 configures the UE's repor...

Embodiment 3

[0067] The MDT system proposed in embodiment three is as Figure 4 shown. The network entity knows the MDT-related capabilities of the UE, and the measurement, logging, and reporting mechanisms are configurable. This mode is suitable for some mobile phones customized by operators. In this case, since the network side knows the UE's MDT capability, it does not need to report the UE's capability. As for whether to enable the MDT function, the two methods in the first embodiment may be used. In this embodiment, the logging and reporting capability module 105 on the UE side can be omitted, and meanwhile, the process of reporting the capability of the UE is reduced.

Abstract

The invention discloses a method for MDT (Minimization of Drive Tests), comprising the following steps that: UE (User Equipment) receives indication information for starting the MDT from a network entity; the UE measures and records measuring parameters associated with the MDT, and / or records MDT associated events, wherein the recorded contents are taken as a measuring log; and the UE reports therecorded measuring log to the network entity. The invention further discloses a system for MDT. The MDT scheme provided by the invention provides a clear MDT start triggering mechanism. Based on above invention design, the embodiment of the invention provides various selectable schemes, thus operators can select the schemes to use according to different requirements and network stages.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for minimizing drive testing. Background technique [0002] In the current network optimization of mobile communication systems, the road test is usually used to check whether the network coverage quality and system performance meet the expected requirements of the design, that is, professional network optimization personnel drive the measurement vehicle to walk randomly, and the measurement terminal records the data during the walking process. Events and measurements are provided to operators for network optimization decisions. This type of drive test is done manually, which requires a lot of manpower and time, and brings a great burden on the network construction and maintenance costs of operators. On the other hand, road tests can only be performed outdoors, but not indoors or in some private areas. Network optimization in these locations is d...
